Hello everyone,
I thought it might be useful to others to update this thread. Based on the readings I made earlier I ordered .039 Audionote tin foil capacitors. I soldered one capacitor per leg to the signal carrying wires of an XLR cable. That did not work. The voltage drop was wrong and the sound was too.
I then tried wiring the capacitors in parallel to double the capacitance (.078). To do this I used a parallel set for each leg of a balanced cable. Four capacitors made one cable. Since I already had the four capacitors, and suspected the impedance to have doubled, I thought it was a worthwhile experiment. This setup got me much closer to the desired voltage drop.
I then ordered Audionote tin foil .082 capacitors. I chose Audionote because they offered the closest to the capacitance I needed for a reasonable price. Success! One Audionote capacitor per signal leg gives me a .27 voltage drop. That is close enough for me. I will allow the caps to break in for a while and then decide if I need to find a higher quality cap. For now I like what I am hearing. Better highs, and more midrange impact. I believe that .080 would give me the preferred drop of .3 volts. I have not found a capacitor of that value searching on line.
I believe the Aragon 8008x5 has an input impedance of 50K single ended, and 100K balanced. I made my cables using Nuetrik connectors and Canare cable.
Thanks for all the help!
